Discussion on Causes and Countermeasures of High-Voltage Distribution Transformer Failures
The article addresses the rising incidence of high-voltage distribution transformer accidents, analyzes the causes of failures, and proposes preventive measures to ensure the normal operation of transformers and the safety of the power system. It points out that failures of low-voltage lines and equipment, overload or short circuits, and moisture-induced insulation degradation of windings can lead to winding damage.
